Security8.8.3
Redis 8.8.3 Security and Stability Release
This release includes critical security fixes for transaction ACL bypasses, cluster bus authentication warnings, and crash prevention in TimeSeries and Vector Sets. A new cluster-bus-port-protected-mode option allows nodes to enforce authentication on the cluster bus port.
Update urgency: SECURITY: There are security fixes in the release.
Security fixes
- #15673 Commands queued in a transaction could still access keys whose ACL permissions were revoked before the transaction was executed
- #15722 The cluster bus protocol has no authentication of its own unless
tls-clusteris enabled, so any host able to reach a node's bus port could join the cluster and threaten it. A cluster node now warns at startup when its bus port is left unauthenticated, and the newcluster-bus-port-protected-modeoption (defaultno) makes refusing to run in that state an explicit choice: set it toyesand the node starts only whentls-clusterauthenticates the bus - TimeSeries: Prevented Redis from crashing when adding samples to a compressed Time Series key restored from a malformed RDB payload
- Vector Sets: Deeply nested JSON used in Vector Set queries could cause the server to crash
